The signals from Johnson in the past week were that he was looking for a Northern Ireland backstop (and that was reflected in informal comments from Irish politicians, commentators and business representatives after talks with him or government negotiators) and was ready to throw the DUP under the bus if he could more than compensate with pro-deal Labour votes. A border down the Irish Sea and use of a different font and he could bring back Theresa May's deal for the 4th (5th?) time. Today he has ruled that out (in his farcical People's PMQs on Facebook) - so back to seeking unicorns!
